Biologically active dietary supplement for correction of exchange disorders in nervous system diseases

The prescription composition of the biologically active dietary supplement (BADS) Oleopren Neuro has been scientifically substantiated through the pharmacological evaluation of the effective agents, polyprenols being the main of them. The technology of an innovative product has been developed, with the establishment of adjustable production parameters securing high organoleptic advantages and stability of the BADS. Regulated indicators of quality and nutritional value have been determined. Sanitary toxicological and hygienic safety indicators of the product under development had been studied, which allowed to establish a shelf life of two years taking the safety margin of three months into account. The possible mechanisms of the dolichols effect on the metabolic status of the organism were considered. Clinical trials of the efficiency and functional focus of a specialized product on a representative group of patients with the dyscirculatory encephalopathy (DE) of vascular genesis stages I ­ II were conducted. The BADS were included in the diet of patients, along with the basic therapy, one capsule twice a day for 10 days. The materials obtained in this article allow to recommend the developed product as an efficient means of increasing the body's resistance to adverse effects of the environment, stressful situations, as well as psychoemotional and physical stress.

[Antibacterial effect of peptide conjugates with a quaternized chitosan derivative and its estimation by the method of atomic force microscopy].

We obtained a number of conjugates based on a quaternized chitosan derivative and antimicrobial peptides (melittin and warnerin) crosslinked by microbial transglutaminase. We determined the optimal conditions for the synthesis (30 minutes, with a mole ratio of peptides and chitosan derivative of 1.4: 100) and studied the antibacterial properties of obtained conjugates. The antibacterial effect of the conjugates was found to be greater than that of their components. The antibacterial activity of the conjugates was determined by the double-dilution method and by atomic force microscopy.
